Aircraft Destroyed After Maneuvering and Impact with Right Wing Low (N70MT)

Calhan, CO, US

On November 21, 2005, an American Champion 8KCAB (registration N70MT) was involved in an aviation accident near Calhan, CO. Investigators recorded the probable cause as: the pilot's failure to maintain aircraft control. Factors contributing to the accident were the low altitude, and the resultant stall/spin. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

An airplane was destroyed after impacting terrain in a right-wing-low attitude following maneuvering with altitude variations between 4,990 and 1,390 feet AGL. Examination revealed accordion crushing on both wings' leading edges and no system anomalies.

Accident Overview

Radar data indicated that the airplane was maneuvering before the accident, with its altitude fluctuating between 4,990 feet above ground level (AGL) and 1,390 feet AGL. The aircraft subsequently impacted the ground in a right wing low attitude on a heading of 230 degrees. The impact resulted in the destruction of the airplane.

Damage Details

Both the left and right wings exhibited accordion crushing along the entire span of the leading edge. This type of damage is consistent with a high-energy impact. The extent of destruction was total, with no part of the airframe remaining intact.

Systems Examination

An on-scene examination of the airplane's systems revealed no anomalies. Investigators found no pre-existing mechanical or electrical issues that could have contributed to the accident. The aircraft appeared to be functioning normally prior to impact.

Maneuvering and Altitude Changes

The radar data captured significant altitude variations during the airplane's flight path. The aircraft descended from 4,990 feet AGL to 1,390 feet AGL and then climbed again, indicating dynamic maneuvering. The final descent ended with the impact at a right wing low attitude.
